EDIT on packed decimal
Hi guys,

I'm tryning to modify a field but I'm stuck. The field is a P15 and is a combined field. The first 12 positions is a field and the last 3 position. The problem is that the last field is not always 3 positions. For example 111111111111222 can be a value, but also 11111111112 can be a value.

I would like to separate the field with EDIT(FIELD, '99999999999$$$') but this gives incorrect data. It probably has something to do with the field properties (Alfa). Does anybody has suggestions to use EDIT on a P field?

You might look into the UFMT routine. We used it in the mainframe FOCUS days, unfortuneately it does not work when pulling data down to an ASCII based machine and then trying to do so. Of course you might be able to do defines in the MFD. We finally had to have a DB2 view set up to solve our problem in getting packed dates extracted from a DB2 column. Part of the Y2K conversion that occurred on our student system.

Frans, try to convert the P field to Alpha first using the PTOA function.

A_FIELD/A15 = EDIT(PTOA(PFIELD,'(P15)','A15'),'999999999999');

This example might help:

-* Convert P format to A format if necessary
-* -SET &BIGNUM = PTOA(&PBIGNUM, '(P15)', 'A15');

-* Number to parse
-SET &BIGNUM = '1234567890123';

-* Get the length of the number
-SET &LBIGNUM = &BIGNUM.LENGTH;

-* Store the first 12 characters in &MYFIELD
-SET &MYFIELD = SUBSTR(&LBIGNUM, &BIGNUM, 1, 12, 12, 'A12');

-* Get the length of the position
-SET &LMYPOS = &LBIGNUM - 12;

-* Get the starting index of position in the entire number
-SET &MYPOSIDX = &LBIGNUM - &LMYPOS + 1;

-* Get the position value
-SET &MYPOS = SUBSTR(&LBIGNUM, &BIGNUM, &MYPOSIDX, &LBIGNUM, &LMYPOS, 'A&LMYPOS.EVAL');

-TYPE field    (&MYFIELD)
-TYPE position (&MYPOS)

Sean

This will get you some of the way there. There is a problem with the data, though - how do you determine what part of the 'combined field' is the 'field' and what part is the 'position'. In 111111111111222, the 'field' is 111111111111 and the 'position' is 222. In 11111111112 (which, since it's numeric can be considered as 000011111111112), the 'field' is 000011111111 or 11111111 and the 'position' is 112 - which I don't think you want.

DEFINE FILE CAR
TEST1/P15 WITH COUNTRY = IF COUNTRY EQ 'ENGLAND' THEN 111111111111222 ELSE 11111111112 ;
TEST1D/D15Lc = TEST1;
TEST1A/A15 = RJUST(15, FTOA(TEST1D, '(D15Lc)', 'A15'), 'A15');
FIELD1/A12 = SUBSTR(15, TEST1A, 1, 12, 12, 'A12');
FIELD2/A03 = SUBSTR(15, TEST1A, 13, 15, 3, 'A03');
END

TABLE FILE CAR
PRINT
TEST1
TEST1A
FIELD1
FIELD2
END

Hi guys,

Excuse me for my late reply, but I have found a solution. This is the code I used:

quote:
DEFINE FILE SORITACT
TEST1/P15 WITH SLEUTEL=IF SLEUTEL GT 999999999999 THEN 111111111111222 ELSE 11111111112;
TEST1D/D15Lc=SLEUTEL;
TEST1A/A15=RJUST(15, FTOA(TEST1D, '(D15Lc)', 'A15'), 'A15');
FIELD1/A12=SUBSTR(15, TEST1A, 1, 12, 12, 'A12');
FIELD2/A03=SUBSTR(15, TEST1A, 13, 15, 3, 'A03');
FIELD3/D12c=EDIT(FIELD1);
VOLGNR_N/D12=EDIT(FIELD2);
RITNR_N/D12c=IF FIELD3 GT 9999999999 THEN FIELD3 / 10 ELSE IF FIELD3 GT 99999999999 THEN FIELD3 / 100 ELSE FIELD3;
END


So I used most of the code of Francis, but the last 4 digits of the field are always 0000. So the FIELD3 could be 9001362700 with FIELD2 009, and 90013627000 with FIELD2 010. With RITNR_N I resolved this and now all the data is correct! All thanks for the input!
